    TLDR

    LIKE A FLY IN THE SPIDERS WEB

    says religion holds back science
    votes for tory government who actively discourages people from going to university

    maybe I should actually block you LOL

    I never claimed I blocked you, nor did I. Why are you changing the topic and avoiding the point?

    You blame religion for a lack of scientific progress, when our Tory government (who you undoubtedly support or voted for, unless you voted for UKIP which is likely) when they actively make students pay almost £30,000, and have not emphasised STEM degrees in the slightest. Pathetic.

    Scientists have discovered an earth-like planet orbiting around our nearest star, 4.2 light years away.

    Currently named Proxima b, new technologies over the coming centuries would mean that the planet could be accessible one day.

    So, we could be living just a few kilometres (well, 40 trillion) away from extra terrestrial life forms :shock:
    Fixed.

    Sadly I think it'll be at least another 600 years before we see any kind of interstellar craft of any capability, possibly even longer.

    I really need some evidence that interstellar space travel is possible, all these claims are just the same as gods goblins and ghosts, even communication between such distances is not obvious, disregarding the fact that any other sun may be sterile of life, or at least intelligent life.

    Imagine if every human and country just binned of *****y religion and wars for greed and pooled resources together towards space and science
    Only about 10% of people in this country have worthwhile ideas (less in the less developed world) and only another 40% of people are really required for manufacturing and fulfilling our needs.

    Moral of the story, half the population is useless and at least materialism gives them something to do.

    It's possible that it may be habitable in the sense of having water and an atmosphere we could breathe however the chances of developed life are minimal on the basis of radiation and being tidally locked.

    To have two planets in our nearest star system though is a great sign.

    Nothing's over buddy, I never even mentioned you on that page, let alone 'blocked' you. LOL. Did you just choose a random time when I said I blocked someone and hope I would not check who I was replying to? Pathetic.

    But you're obviously avoiding the point because you know its true. Whinging about religion holding science back is ridiculous. Especially when people like Isaac Newton, Gallileo, Guass, Kepler, Faraday, Maxwell, etc were all CHRISTIAN.

    The reason we aren't advancing is because of the commercialisation of education, thanks to the Tories, who you probably support.
    Are we not advancing? The UK space industry is going from strength to strength and we're on track to have a 10% market share by 2030.

    Christianity in Europe is clearly geared more towards prosperity than other religions.

    Heard of this somewhere...I suppose it's part of the Alpha Centauri??

    Forgive me if I'm mistaken, but alpha centauri has been discovered a while back with research showing that it could potentially support human life
    Alpha Centuari is the name of the star system (it's a trinary system with one star like our sun). Based on findings from Kepler it's likely that most stars have planets around them, the number of earth like planets alone is speculated to be between 4-17 billion.

    We should find a lot more earth like planets from next Autumn when TESS goes up. Whereas Kepler looked at one part space but thousands of light years deep (which is why we've found lots of good planets hundreds of light years away), TESS will scan the whole sky with the aim of observing the nearest 200,000 stars. Since we live in a relatively dense stellar neigbourhood there are over 30 stars within 16 light years that may have habitable planets (i've excluded binary/trinary systems plus white and brown dwarfs).

    Not so downbeat as that personally, i think sometime around 2200.

    It's very probably that ITER will work properly in which case fusion is viable in the 2060's. Allowing for some time to make those reactors smaller then we get a probe to the star system early in the 2100's.

    We already have a mathematical formula to go faster than light and are attempting to experiment with anti-matter so allowing another century we get out there in the early 2200's.

    This is what they are thinking of sending in the future. Its an interesting read even if we might be a fair bit away from it potentially happening

    Here's the problems with finding Earth like planets: they have to have so many factors combined together that need to be suitable for life as different factors affect each other (always hear about how planets can have liquid water when in the habitable zone... Ignoring air pressure). Then also we can barely measure that many things about planets at the moment. Using the transit method we can guess the orbit and then with that and the size of brightness drops the size of the planet. We can't tell what orbit the planet follows (that's impossible), we can't tell how fast it spins on its axis (that's impossible) and it's incredibly hard to find elements in the atmospheres of Jupiter sized planets at the moment.Now onto space travel. Using anti matter or this FTL equation to create a new propulsion system is going to be horrendously hard. Then also the distances anyway are just too far away. Alpha Centauri is 4.2 light years away and a group called the 100yearstarshipproject said that if you travelled at 1000x the speed of voyager (35700000 mph) it would take 70 years to reach alpha Centauri. That is our closest star, some of the possibly habitable planets are several hundreds light years away.

    There's then the issue of just building the ship itself. You need to have a very large crew due to the issues of generations of inbreeding resulting in genetic diseases. This requires a horrendously large ship and then you need a source of food on the ship... Making it larger, you need to protect the crew from debris in space and also from radiation and it also needs to provide artificial gravity... Which the main idea is to spin the ship which will be a lot of fun. Constructing such a ship is even a bloody ridiculous task itself because the ship will be impossible to launch on earth so needs to be built in orbit and will require a god awful amount of funding and resources.

    Edit: sorry about the lack of paragraphs, my phone decided to ignore the fact that I separated several lines and put them together making 2 stupidly large paragraphs.

    Theoretically if fusion pans out then we should be able to reach about 10% the speed of light so getting a probe there in decades is possible potentially.

    I don't think we'll go down the generation ship route, it's very impractical. I think we'll probably see the solar system crawling with ships and bases but until we get interstellar technology probes are all that will reach other planets.

    Don't count on it. We've been trying to sustain a fusion reaction for the past 60 years. Although I always see that we only discovered flight 100 years ago and we have A380's flying around today.

    Even if you can generate the power, then shrink it, you still need a propulson mthod that isn't chemical based or doesn't have a reaction mass to actually do anything. When you compare Fusion power to the actual amount of energy required to reach anywhere near 25% the speed of light Fusion looks bit weak. We might need somthing better than Fusion tbh.

    Even then, at 25% SOL you can forget exploring all but the absolute closest star systems.

    If you send your first probe unmanned, which it will be, it will need some kind of adaptive AI to control it since it will be so far to control even with flight computers.

    You'll also need a whopping transmission dish and power supply to return any data. Voyager 1's signal, having just left the solar system is starting to get a bit thin on the ground and that's using a lot of recievers.

    As for a ship, any realistic lifesupport is still a big problem, as is artificial gravity or any kind of suspended animation. All these tech's for interstellar purposes are at least 200 years off.

    When I said 600 years I was thinking somthing aproximating the capabilty of, perhaps warp drive. Remember if you send a ship, you've still got to slow down when you get there.

    I've no doubt we'll try and launch a probe with a 30 year trip for a flyby when the tech is up but that's quite a wait for just a flyby. I'd really like to see that in my lifetime.

    They are talking about sending nano craft at 20% speed of light to photograph it etc. May be feasible to get a look at this world in our lifetime, who knows
    Still unlikely that would still take 20 years to get there. And 20 years to get back (unless they send the photos back faster but how could they do that at such distance with nothing to boost/receive the signal in that vast distance). That's already 40 years and how many years til they have figured out how to build a craft that can travel at that kind of speed for 40 years...

    I can see that happening with us sending probes to planets, we would need to send probes anyway to far away planets to measure factors of habitability.

    I would probably think we would need to go down the generation ship route if we were to go on a habitation mission because of the large distances we are from possibly habitable planets. I don't know what speeds we could achieve with the FTL equation but I imagine it won't be 10x the speed of light and so we would still take several hundred years to reach a destination.

    Pedantically speaking, its been known for quite some time about a habitable planet around our nearest start. Heres a pic of it. Here is a close up view of the same planet.

    We would have military bases on Mars by now. It would serve as a space base while preparing to go to war with those Andromedan *******s who are about to invade us.
